Sounds like one of those chimers they put on uhaul trucks when you hit the governor real annoying.

My truck is a n early 99 and mine dings at 74 and goes off around 72. i called the ford dealership and talked to the service guy and he told me it was a n option on fleet trucks, its programed in the computer. I just turn the radio up when it starts dingin....

Sounds to me like you've unplugged the GEM (Generic Electronic Module). I had a gremlin in my truck for awhile that turned out to be that same cable you've disconnected. The GEM controls the interior lights, the door chime, and a few other things.

No door light and the things runs like a top all the way to 95 just the
chiming.
At work today i started the quest to find the stupid little thing. And i did its on the back of the fuze panel. At first glance it lookes to have two sets of about 8 or so wires coming out of each connecter. So i took the panel loose and turned it over to see that one is just in a "dummy" spot molded into the caseing i unplgged it first to see no little "prongs" for the connectors to conect to and the other one was what was really pluged in. When i unplug that one i have no lightes in the cab of the truck but the chiming does go off. And both of the connecters are the same kind but i dont want to just go plugging different connecers togeather.

Its pretty hard to explain. And i know that your confuzed by now.

Thanks Alex

Stroked383, what you are hearing is the overspeed indicator. You can go to the stealership and have them reset this to a higher speed, or just turn it off. Like Farmboy said, it's a fleet option to keep drivers below the speed limit and it defaults to 75MPH. Call a dealership with a FLEET service, and they should have sufficient experience with this kind of stuff that they can turn it off (disable) it for you.

I should know, I used to work on the Truck BCE part of the Ford Tech Hotline.
